LUBRICATOR-PUMP.

To all whom it may concern:

Be it known that we, GEORGE J. ARENDs and JOHN J. ARENDs, both citizens of the United States, and residents of Rock Rapids, in the county of Lyon and State of Iowa, have invented a new and Improved Lubricator-Pump, of which the following is a full, clear, and exact description.

Our invention relates to improvements in lubricator pumps, and particularly to such as are employed in the cylinder lubrication of heat engines, in which a reciprocating plunger, playing in an oil pumping cylinder, operates in conjunction with a kinematic element of the engine; and the objects of our improvements are first, toassure continuity in the oil feed to the pump; second, to afford facilities for the necessary preheating of the oil to be delivered to the pump; and, third, to provide expedients in the regulation of the oil delivery.

We attain the objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevational view of our lubricator pump, showing the same as applied to the cylinder of a horizontal steam engine; Fig. 2 is an enlarged sectional elevational view of the lubricator pump taken through the oil reservoir and certain parts of the pump and valve mechanism and delivery outlet; Fig. 3 is a rear side elevational View of the same on the same scale as that of the preceding view; Fig. 4 is a sectional elevational view of the same taken on the line l4t of Fig. 2, in the direction indicated by the arrow; and Fig. 5 is a cross sectional view of the same taken on the line' 5 5 of Fig. 2, in the direction indicated by the arrow. j

Similar characters of reference designate like parts throughout the several views.

13 is the oil supply reservoir for the lubricator, which has an integrally formed head h having a central externally counterbored perforation for the reception of a vertical steam pipe 6. It is fitted by a screw thread to a lower centrally and similarly perforated cap 1 having an internally threaded integral outlet nipple 4 The steam pipe 6 passes likewise through the perforated cap 1 and is packed at 9 at the upper extremity of the reservoir B and at the lower end thereof. The lower packing is designated as 1 and is forced into the counterbored perforation and similarly Specification of Letters Patent. Application filed May e, 1908.

against the pipe Z), by the adjacent end face of a coupling 72 screw-threaded to the terminal of the said pipe. The office of the steam pipe I) thus disposed, is to supply heat to the lubricating oil contained in the reservoirB, as'will be more fully hereinafter and formed exteriorly on the steam inlet pipe B ,is a screw thread B which, when the lubricator is in operation and connected up to a steam engine as in Fig. 1, taps radially the way P of the throttle valve V of the engine. The lower sections of piping comprise the nipple 1 screw-threaded to the coupling n, carrying and fitted to the tee 2", having a neck a". From the tee 2 depends the threaded nipple 3 fitted to the ell 5 the latter carrying a horizontal pipe 6", to the terminal of which is screwthreaded an upright portion in alinement with the depending inlet pipe B This consists of an ell 7 screw-threaded to the terminal of the pipe 6 trued up for the reception of a long nipple 8 to which is threaded a nut 9 a union Z2, an internally threaded flanged nipple Z2 and a flanged branch b having an oil spout 6 having a tapering external nipple thread b which taps the valve way P of the valve V, and diametrically opposite the inlet pipe at the nipple threaded portion 13 is coupled with the union nipple V, which as well as the union is made steam tight by the gaskets b" and b respectively. The spout 6 is choke bored and is bent at its termlnal b to direct the delivery laterally.

The disposition of the piping just described provides in eifect a rectangular loop,

and when a draft of steam is directed toward the engine cylinder and valve chest A via the valve way P, a portion will be scooped up the pipe B through the elliptical opening B of the inlet B and shunted around said pipe loop and emergefrom the spout b, passing along with the current of steam via the Way P to the engine. The elfect of the steam loop circulation, thus effected, will obviate condensation as well as maintain a continual supply of heat for the pipe 6, wherewith to heat the oil in the reservoir 13, in order that its viscosity may be reduced to a sutlicient degree to facilitate its being pumped by the injector mechanism through the spout b of the pipe loop, to the engine.

The pumping mechanism of the lubricator consists primarily of the pump cylinders C and it set at right angles to each other and which lie in the same plane, and, respectively, pelpendicularly and horizontally disposed within the pipe loop and adjacent to the reservoir ll and pipe 6" respectively. The cylinder C is carried in the outlet nipple P of the lower cap 1 of the reservoir B, by a straight away needle valve casing 8; this latter has an integrally formed branch nipple 5 externally threaded, which is engaged with and secured in the outlet nipple 4: The latter is faced oil on the end and opposes a plane annular shoulder 7 similarly formed around the base of the nipple 5 and between these two faces, carried by the nipple 5, is a packing ring 3, to effect a tight joint thereat. A packing ring 2 is similarly disposed between the lower terminal of the reservoir B and the seat of the cap 1.

The bore of the valve casing 8, has a threaded counterliioring 9 at its upper end, into which is screw threaded the lower terminal of the pump cylinder C and the cylinder C is bored in common with the bore 8 Within the bore of the cylinder C and adapted to vertically reciprocate therein, is a cylindrical plunger piston 3 provided with an elongated concentrically disposed extension or stem l The piston 3 is of sulficient length to make a stroke vertically downward in the cylinder (land the bore S of the valve casing 8, and project to some extent beyond the upper terminal of the said cylindcr. The upper terminal of the cylinder U is made l'luid tight with the piston 3 by a stulling box 1, screw-tln'eaded thereto, and a gasket 9F.

The lower terminal oil. the bore 8 of the valve casing 8" has a neck C which is counterlmred at its lower terminal to form a ball valve seat (3 into which is thrust by a spiral spring C a ball valve (i The lower terminal. (l of the valve casing 8, is conct-mtrcally counterbored wth the bore 8 and neck (1 to reach the scat C and is internally thrmuled to receive a bushing C, which carries an oil drip spout i. The upper terminal of the bushing serves as apedesta l for supporting the lower extremity of the valve spring E The terminal C of the valve casing R is externally threaded to fit an internally threaded union coupling 0 to which is coupled by a flanged head, the casing (1 of a sight glass (l Resting upon the upper terminal of this casing and jammed fluid tight with and against the upper end of the glass C and the annular surface of the terminal C of the valve casing S by the union coupling 0', is an annular, centrally perforated gasket 1 through which the oil spout 2' is thrust. The casing C" is internally screw-threaded at its lower ter minal, and has lateral windows I) through which the glass U and its contents may be seen.

The horizontal pump, comprises a cylinder (1 similar to the cylinder U; and is carried by the neck 41:" of the tee fitting 2, the nipple S" screw-threaded thereinto, and the tee fitting (3 screwed thereto, carrying the sylinder (1 similarly secured. The tee fitting (3" has its branch nipple presented vertically to the casing (1" and is screw-threzuled into the adjacent: terminal thereof and carries on its annular face a packing ring 1 which a llords a fluid tight union thereat with the lower tOllllllHll of the sight glass G. The tee titting 6 has a branch bore 7 common wit h the bore of the cylinder (l, andv a vertical bore 2" coincident with that of the bore of the glass (i The cylinder 03 is provided with a piston 9 stutling box 1 and packing ring 2 disposed relatively as already described in connection with the correspomling parts for the cylinder C. The piston. 9" has a stem 3" similar to that of the stem 45- ot' the piston 3" The bore 7" of the fitting t3 terminates in an annular neck j, which is counterborcd at its outer terminal to seat a ball valve 5 by a thrust spring l pocketed in a eounterbored tubular bushing l.

The control of the oil feed from the supply reservoir B, is eli'ected by a tce-handled needle valve 1 (Fig. 5), which is screwthreaded in the branch outlet El" of the casing S and made fluid tight by a packed stulling box 2 Toward the inner terminal of the needle valve 1 and angularly ln'anching therefrom to a cylindrical surface, is a port (3", which terminates at the opposite oxtremity at the entrance to the nipple 5". The conical terminal of the needle valve 1* has a, corresponding seat in a lateral. inlet to the bore 8, which will be apparent by reteronce to Fig. 5. The port (3 is adapted to establish communication with the bore 8 when the needle valve 1 is backed olli' sulliciently to uncover it. In Fig. 5, the needle valve l is shown closed and the oil feed from the reservoir 13 to the pumps is cut oil.

The driving mechanism for the vertical and horizontal pumps just described, is car ried by an S bracket (3 screwed at one of its terminals to the lower cap 1 oi the reservoir B and depending therefrom. The terminals of the S bracket (5 present substantially, when the same is positioned as illustrated, upper and lower oppositely directed arms, the latter of which is perforated and carries a tight fitting tubular bearing S, provided with a flat surfaced head 03, through which is thrust a spindle S carrying at its inner extremity a ratcheted crank disk 7 provided with a hub S and at its outer extremity a crank handle d. The spindle S and the crank handle are fitted in telescoping relation and are secured together by a cotter bolt S To the ratcheted crank disk 7 is secured a crank pin S and to this are fitted in bearing relation, the two driving extremities of each of the pump connecting rods 7 and 5 and an intervening bearing washer W. The stem 4 of the piston 3 carries a set screwed adjustable collar 5 having an integrally formed and radially extending arm or wrist pin 6 from which is terminally swung by the driven extremity, the connecting rod 7 which is held against lateral displacement by. a cap screw in a familiar manner. The connecting rod 5 is likewise swung on the wrist pin 2 of a similar collar 4 secured to the stem 3 of the piston 9 Swung upon the hub S of the ratcheted crank disk 7 is a concentric strap S carrying a depending lever (Z to which is swungv upon a stud (V, a spring pressed pawl d engaging the teeth of the ratchet disk 7 Carried and secured to the depending lever d is an extension bar I, the upper terminal of which is bent fiatwise at right angles and upon this bent portion is secured the stationary terminal of a spring d for the pawl d carried by the lever 65*; and swung upon a stud 9 secured thereto adjacent to the ratchet wheel 7, is a counter pawl 8, which falls upon the perimeter of the ratchet teeth of the wheel 7 and checks any tendency to backlash or reverse motion on the part of the spindle S WVhen the lubricator thus described, is in position and connected to a steam engine A, as illustrated in Fig. 1, the extension bar I is connected by a pitman H to the valve stem E of the engine, by means of a yoke F secured thereto, and a vertically swinging rocker G hung by a bracket from the framework of the engine.

The reservoir 13 of the lubricator has integral with its head it an inlet tap a, the upturned end 1' of which is threaded and into which is screwed a threaded plug 2, having a head and gripping lug 3 The operation of the pump is effected by first charging the reservoir with a supply of cylinder oil'through the uncapped inlet tap c, then capping it by means of the screw plug 2 then opening the needle valve; next turning the spindle S'* by the crank handle d, which will drive both the vertical and horizontal pumps, and by observing through the sight glass C whether the oil is being forced past this point through the spout 2' as desired, whereupon the required adjust: ment of the needle valve will be ascertained. The feeding of the oil referred to, is effected through the rotation of the disk 7, driven upon starting by the ratchet mechanism or crank handle just described, which drives the vertical and horizontal pump pistons, and as the oil in feeding past the needle valve 1 by gravitation, reaches the bore 8 of the cylinder C, the piston 3 forces it, on its downward stroke, to open the ball valve C and pass thereby through the spout 2' via the sight glass C to the bore 7 of the cylinder (Z. In the meanwhile, the piston 9 following the stroke of the piston 3 at 90, will force the oil past the spring-seated valve 5 and the oil will circulate with the steam draft down and around the lower piping through the'perforated bushing 4 nipple 3 ell 5, horizontal pipe 6*, up the ell 7 to the vertical pipe 8 and discharging oil spout b into the valve chest A.
